I did. Her name was Laura.
We were friends but then she started going weird and copying me with everything.
So I'd start doing things she wouldn't or couldn't do. But it didn't stop her trying.
So in the end I just got mad and shouted at her.
And then she got mad and started spreading rumours.
And we were enemies since, competing in everything. :3
And when we left school she signed my guestbook with:
"Nikita, I've never understood why you hate me but I've never hated you"
(Which was a big lie, because you could tell she hated me. Everyone knew it.)
"Good luck in the future. Hope you get into a good college x"
Psh. She meant the complete opposite.

i had recently moved to a new house so I had to move to a new tkd school since my old one was too far now. the first day, i had a match fight with this girl who totally beat me because I was so much less experienced than her. a few months later i start going out with this guy that she likes and she still attempts to flirt with him even though he totally ignores her. eventually i became more skilled than her after a year and i totally owned her in match fights. shes always a bitch but now she knows her place.
